Be it known thatI, ROBERT V. VVARGA, a citizen of the United States,residing at St. Louis city, in the State ofMissouri, have invented newand useful. Improvements in ivindow Locks, of which the following is aspecification. I Y

This invention relates to window locks and its principal object is toprovide a window lock which will lock and positively hold the window inany raised position.

An object of the invention is to provide a lock of this characterwhich'embodies a;

toothed or serrated bar to be carried by one segment for engagement withthe tooth of the serrated bar to hold the two sashes in locked positionwith respect to each other.

With the preceding and other objects and advantages in view, theinvention consists in the'novel combination of elements and arrangementof parts and operations to be hereinafter specifically referred to,illustrated in the accompanying drawings, and pointed out in theappended claim. 1

In the drawings;

Figure 1 is a fragmentary elevation of a window having my inventionassociated therewith. r v

Figure 2 is an enlarged fragmentary 'sectional view of the window havingthe invention applied thereto, the invention being shown in elevation,and

Figure 3 is a top plan view of thetoothed segment and its mounting.

Referring to the drawings in detail wherein corresponding characters ofreference denote corresponding parts throughout the several views, thenumeral 5 designates an Lshaped plate having openings 6 therein toreceive screws or other fastenings 7 to hold the L-shaped plate to theupper face of the lower sash as shownv in Figure 2.

of the window sashes and a pivoted toothed Extend- 7 ing from the L-sha'ped plate is a pair of up- 7 Standing ears 8 to'which a triangularshaped locking segment 10 is pivoted, as indicated at 11. Thistoothedisegment has its inner edge provided with teethor corrugations12.

Extending along one of the rails of-the upper sash and secured theretois a-rtooth or serrated bar 13 whose ends are secured to the sash bymeans of fastenings 13. The toothed or locking segment can be swung onits pivotto engage ordisengage the same from the toothed or serrated bar13 by grasping-the same at. a. point indicated by the reference numeral14.
